uchardet autopkgtest fails on i386

[Balint Reczey]

In i386 autopkgtest the build-essential dependency of uchardet "build" test is satisfied from amd64 which causes amd64 gcc not finding the i386 ucharded library pulled in by libuchardet-dev.

The debian/test/build needs a fix similar to what has been done for e.g
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=946535

see http://launchpadlibrarian.net/459718227/libxcb_1.13.1-3_1.13.1-3build1.diff.gz for a debdiff example

I have submitted a merge request to mark the test as bad.

Wearing my Ubuntu Core Dev hat I don't want to carry this as a delta and wearing my DD hat I would not find a request to carry such change in many packages of Debian reasonable either.

Making autopkgtest cross-testing capable is the most promising approach IMO, till then the hint will be enough.

@rbalint, Debian has been taking those patches, why do you think it's not suitable there?

https://packages.qa.debian.org/d/dbus-glib/news/20191209T190455Z.html
https://packages.qa.debian.org/libv/libvncserver/news/20200102T144801Z.html
https://packages.qa.debian.org/r/raqm/news/20191217T093434Z.html

to list some examples if that helps...

@seb128 It is extra code that goes away when autopkgtest is fixed. Having a hint that can be removed when autopkgtest is fixed is the least work as I see.

This bug was fixed in the package uchardet - 0.0.7-1

uchardet (0.0.7-1) unstable; urgency=medium
